Abstract: A process for demineralizing and agglomerating coal in which the coal is subjected to pulverization in order to separate mineral matters therefrom and resulting coal particles are agglomerated through the use of a bridging liquid and a binder. Oversided coal particles are recycled in a grinding circuit until they are reduced to an acceptable size and bridging liquid is removed from the microagglomerates of coal in a low shear reactor and recovered for reuse in the process.

Abstract: A process for selectively removing hydrophilic constituents from flowable hydrophobic mixtures and suspensions which comprises forming a tenacious paste by mixing water with finely divided material which is insoluble or substantially insoluble in water and in the organic liquid in the hydrophobic mixture or suspension, which is inert to the organic liquid and the hydrophobic materials in the hydrophobic mixture or suspension and which is capable of selectively adsorbing said hydrophilic constituents. The paste is formed in a mixing-type liquid-liquid contactor so that a layer of the paste forms on and clings to the impellers and other internal surfaces of the contactor.

Abstract: Calcium oxide particles are suspended in an inert, water-insoluble, organic carrier liquid. While the suspension is agitated, phosphoric acid and water are added whereby to form agglomerates consisting of dicalcium phosphate useful in animal feeds.

Abstract: An aqueous pulp or slurry containing cement copper particles is treated with conditioner and hydrophobic bridging liquid to form agglomerates of the cement copper particles, which agglomerates are then separated from the aqueous phase.

Abstract: An aqueous dispersion of a clay is dewatered and the clay solids thereof are agglomerated using a conditioner and a hydrophobic bridging liquid.

Abstract: Steel mill wastes are treated to recover the iron values thereof by a two stage agglomeration process wherein relatively small size first agglomerates are formed by agglomeration of steel mill wastes from an aqueous suspension thereof and then relatively large size second agglomerates are formed by agglomeration of said first agglomerates from a suspension thereof in a hydrophobic organic liquid and simultaneously a reactant chemical reacts with the agglomerates to provide a solid binder material formed in situ during the second agglomeration procedure.

Abstract: An aqueous dispersion of a clay is dewatered and the clay solids thereof are agglomerated using a conditioner and a hydrophobic bridging liquid, and then pellets are formed of the clay agglomerates.

Abstract: Finely divided sulfur particles in a liquid suspension are agglomerated by adding molten sulfur to the suspension and agitating the mixture to transform the particles into agglomerates wherein the finely divided sulfur particles are held together by the previously molten, now solidified sulfur, acting as a binder agent.
